Yes and yes.
Come up with their own respective bios and post them in the bio topic, then you'll be free to post.
They prefer to use oil and all sorts of powder to power their machines and weapons, as those are the easiest to get/make in Boomtown.
They (mostly) aspire to set aside their political differences and live in peace in Boomtown, politics that doesn't directly pertain to Boomtown is not talked about by the majority of the citizens.
The weapons are solely Western-style, but each citizen comes up with their own unique twist. I encourage you to do the same.
Lucky knows that they exist, of course, but doesn't think it worth his valuable time to interfere with the official "township", seeing as the town brings many barrels of oil and crates of rare minerals into Aethasia, things that are rare, considering how much Lucky has drained the resources of the rest of Aethasia.
Automatons do not patrol, Lucky basically ignores their existence, since they're not a threat... yet.
